摘要
本文运用模糊数学理论建立了大豆灰斑病预测预报模型。经对国营350农场种植的大豆中熟品种“合丰25”十年的资料拟合,符合率达90%,对中熟品种“黑农26”九年的资料拟合,符合率达89%,对早熟品种“黑河3号”九年的资料拟合,符合率达78%。
In this paper a model for predicting and forecasting Cercospra Sojina has been built by the use of the theory of fuzzy mathematics. The accuracy of the model reaches 90% by analysis and estimation of the ten year's data collected from the middle maturity cultivar Hefeng 25 on the 850 State farm, 89% by analysis and estimation of the nine years'data from the middle maturity cultivar Heinong 26,and 78% by analysis and estimation of the nine years' data of early maturity cultivar Heihe 3 .
